PROBLEM: The HTML parsing code of Netscape is flawed. A malicious remote
website can execute a buffer overflow causing arbitrary code to run.
PLATFORM:
Red Hat Linux 6.0
i386, alpha, sparc
Red Hat Linux 6.1
i386, alpha, sparc
Red Hat Linux 6.2
i386, alpha, sparc
Red Hat Linux 7.0
i386, alpha
DAMAGE: Through the execution of arbitrary code a malicious remote
website could gain root access.
SOLUTION: Update Netscape, as per Red Hat instructions.
VULNERABILITY The risk is HIGH. The vulnerability has been publicly posted.

1. Topic:
New Netscape packages are available that fix a buffer overflow
in parsing HTML.
It is recommended that all Netscape users update to the fixed
packages.
2000-11-27: Added packages for Red Hat Linux 7 for Alpha
2. Relevant releases/architectures:
Red Hat Linux 6.0 - i386, alpha, sparc
Red Hat Linux 6.1 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc
Red Hat Linux 7.0 - i386, alpha
3. Problem description:
A buffer overflow exists in Netscape's HTML parsing code. By
using specially designed code, a remote website could cause
arbitrary code to be run on the local machine.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
20415 - Netscape segfault - cured in 4.76
20462 - Netscape 4.75 buffer overflow
